What's up with all the different casing standards?

What's up with all these different cases for DVDs? we have Amary Keepcases, snappers, Alphas. Why can't the industry settle on one universal case that will hold any type of DVD and 2 disc set? all this stuff with cases is kinda confusing and each of these cases we have now has at least one disadvantage. Why not just build one single case that can also handle 2 disc sets as well. This has just been on my mind as of late. Any answers as to why? I don't recall this kind of stuff with VHS ( Inever did get into LD.) Why isn't there just one single case?

There was variety in VHS cases though.
Some of the early cases were *huge*. The US has a lot of Cardboard cases (don't know if they all are), whereas the UK has smaller plastic cases.
I'm sure eventually a more common standard will emerge. We've already lost some of the cases (CD Jewel cases, Tall Jewel cases)

I laugh when people whine about the Snapper...remember the infamous Polydor Tray case, where there was a disc in a tray that slid out of the bottom, exposing only half of the disc, virtually guaranteeing that you'd scratch it when removing and replacing it? Now that was one BAD design. No wonder Polydor went belly up. Snappers I can live with.
Image, now that they've gone to keepcases, are using a three-prong variant on the Amaray, but it's very, very fragile. Of the discs I've received in the mail, EVERY SINGLE ONE OF THESE has been broken and the disc floating with the debris. Thanks, but I'd rather have a Snapper.
